Staff Machine Learning Engineer, ML Infrastructure

Were a high-tech home security company thats passionate about protecting the life youve built and our mission of keeping Every Home Secure. And weve created a culture here that cares just as deeply about the career youre building. Ours is a no ego culture of collaboration and innovation where those seeking their next challenge can find big opportunities and make a huge impact on the lives of all those who we protect. We dont just want you to work here. We want you to grow and thrive here.

Were embracing a hybrid work model that enables our teams to split their time between office and home. Hybrid for us means we expect our teams to come together in our state-of-the-art office on two core days typically Tuesday Wednesday or Thursday working together in person and choosing where they work for the remainder of the week. We all benefit from flexibility and get to use the best of both worlds to get our work done.

Well were growing and thriving. So we need smart talented and humble people who share our values to join us as we disrupt the home security space and relentlessly pursue our mission of keeping Every Home Secure.

Were looking for a Staff ML Engineer to join our Cloud ML team the team that owns both the cloud-side ML infrastructure and the applied ML research that powers SimpliSafes intelligent home security products. This is a senior individual contributor role focused on raising the bar for how we build deploy and operate ML systems at scale.

Youll partner closely with other Staff and Principal engineers to drive architecture mentor across the team and set the technical direction for our ML platform. The work spans two of our most demanding workloads: real-time computer vision inference that processes video from cameras and doorbells across our customer base and LLM/GenAI infrastructure that will power our future generation of intelligent applications.

This role is for someone who has built ML infrastructure before knows where the sharp edges are and is energized by making other teams faster and more reliable.

Set technical direction for ML infrastructure

• Drive architecture decisions for our Kubernetes-based ML platform anchored on Ray for inference alongside KServe Triton and vLLM across real-time and batch workloads.
• Lead deep technical reviews on system design capacity planning and reliability for the highest-stakes ML systems at SimpliSafe.
• Identify and remove the systemic bottlenecks in our ML deployment infrastructure whether thats serving reliability deployment friction observability gaps scaling or cost.

Build and operate real-time CV inference at scale

• Own the design and evolution of cloud-side inference systems that process live video and events from SimpliSafe devices in real time.
• Drive throughput latency and cost improvements (batching strategies GPU utilization autoscaling multi-model serving) for production CV models.
• Build the feedback loops between cloud inference edge devices and the data flywheel that improves model quality over time.

Stand up LLM/GenAI serving infrastructure

• Help shape how SimpliSafe serves LLMs in production model serving patterns KV-cache and batching strategies evaluation pipelines guardrails and cost controls.
• Partner with applied ML engineers to take new GenAI-powered product features from prototype to scaled deployment.

Raise the engineering bar across Cloud ML

• Mentor engineers across the team through design reviews code reviews pairing and written guidance a meaningful uplift on everyone you work with.
• Establish and evangelize best practices for model lifecycle management (registry deployment monitoring rollback drift) and on-call.
• Write the documentation runbooks and architectural decision records that make the platform legible and durable.

Own reliability and operational excellence

• Lead incident response and postmortems for critical ML systems; turn lessons learned into platform-level improvements.
• Define SLOs observability standards and on-call practices for ML services in production.

• 8 years of software/ML engineering experience with a clear track record of building and operating production ML systems at scale.
• Deep expertise in cloud ML infrastructure on Kubernetes with hands-on production experience with Ray (which powers our inference stack); experience with KServe Triton vLLM Kubeflow Argo or similar is a strong plus.
• Strong production experience on AWS (EKS S3 IAM networking) and with Kafka containerized deployments CI/CD and infrastructure-as-code.
• Demonstrated experience designing and operating high-throughput low-latency inference systems GPU-aware scheduling batching autoscaling multi-tenancy.
• Solid grounding in ML fundamentals: how models are trained evaluated versioned deployed monitored and rolled back in production.
• Proficiency in Python is required; experience with a systems language (Go C Rust) for performance-sensitive components is a plus.
• Staff-level technical leadership: ability to drive ambiguous cross-cutting initiatives align senior stakeholders and elevate the engineers around you without formal authority.
• Strong written and verbal communication you can make complex technical tradeoffs legible to ML scientists product and other infra teams.

• Hands-on experience with LLM serving in production (vLLM TGI TensorRT-LLM SGLang) KV cache management continuous batching speculative decoding quantization for serving.
• Experience building real-time video or streaming ML pipelines (Kafka Kinesis Flink or similar) at scale.
• Background supporting CV workloads in production model formats GPU/accelerator tradeoffs video codecs.
• Experience with model lifecycle tooling (MLflow Weights & Biases model registries drift detection shadow deployments).
• Open source contributions to the ML infrastructure ecosystem (Ray KServe Triton vLLM Kubeflow etc.).
• Experience operating in environments with strong security and compliance requirements.

The Cloud ML team owns the full surface area infrastructure and applied research which means your work as a Staff infra engineer directly shapes whats possible for the science. Youll have unusual leverage: the platform you build determines how fast SimpliSafe can ship intelligent features and the features we ship directly impact whether someones home is safer tonight than it was yesterday.

• Customer Obsessed - Building deep empathy for our customers putting them at the core of our work and developing strong long-term relationships with them.
• Aim High - Always challenging ourselves and others to raise the bar.
• No Ego - Maintaining a no job too small attitude and an open inclusive and humble style.
• One Team - Taking a highly collaborative approach to achieving success.
• Lift As We Climb - Investing in developing others and helping others around us succeed.
• Lean & Nimble - Working with agility and efficiency to experiment in an often ambiguous environment.

• A mission- and values-driven culture and a safe inclusive environment where you can build grow and thrive
• A comprehensive total rewards package that supports your wellness and provides security for SimpliSafers and their families (For more information on our total rewards please click here)
• Free SimpliSafe system and professional monitoring for your home.
• Employee Resource Groups (ERGs) that bring people together give opportunities to network mentor and develop and advocate for change.

The target annual base pay range for this role is $183500 to $244600.

This target annual base pay range represents our good-faith estimate of what we expect to pay for this role.
